this will not work for me as my server has many web apps (php driven) all 
using the same database - each app having different requirements. What grinds 
me is that some users enter crap searches on my apps and then hit the 
stop/cancel button when it takes too long. I know in upcoming versions of php 
they plan to somehow "fix" this - how I do not know. Oh yes, my

For now the workaround would be to write a daemon or a cron job that connects 
to MySQL once in a while, runs show full processlist, check the execution 
time and command type, and kills all threads that have exceeded the limit on 
select.
